PURPOSE:To restart a motor extremely quickly, by confirming a state from the generation of momentary service interruption to voltage recovery quickly with fixed-cycle handling or interruption handling. CONSTITUTION:The input of power stop/recovery signal A for output generated from a voltage lowering detection circuit 2, to the digital input terminal (D/i) of a processor 3 in a controller is provided, and by the processor 3, voltage lowering/recovery is identified with the signal A. By the processor 3, momentary service interruption recovery detection programs are run, and between the time point of the generation of momentary service interruption and the detection of momentary service interruption recovery, the processor 3 is continuously started in a constant cycle (for example, 5m sec.). When a power source is recovered, then power stop/recovery is discriminated for the recovery, and as a result, normal operation is started by a motor. |
